Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

@@HerrRussoTragik why not a railgun using megnets?
Considering the string would fling humans, which are basically animals, and asteroids are basically rocks, you could exploit that technicality and say: 7000BC: Rock and a string, the ultimate ranged weapon for hunting animals.

Imagine Kurzgesagt develops a space colonization game with all of these elements they've discussed! And this art style would only make it better!
I would pay a lot of money to play that game!
thats literally my dream
Extremely underrated comment
I wish but like, they're too busy making high quality videos for us, what with managing merch too, if they somehow make the game tho I'd absolutely love it
I think someone said this in the comments of their stain sphere video
this is cool and all but just imagine the horror you'd feel missing the tether on your return trip to earth or Mars
I guess you'd still need rocket propulsion as a failsafe. You wouldn't have rockets on the vehicles themselves because the whole point is to phase out rockets, but could rescue vehicles be stationed in orbit to catch anyone that got away?
The tethers fling you much much faster than a normal rocket flies. The amount of fuel required to do a recovery would be more fuel than we have on earth, most likely, as not only would you have to catch up to them (ie you'd need to be flying faster), you'd need to also be able to invert your direction of travel and then slow down again when returning to the planet. Even then, would both crafts have enough oxygen to survive the amount of time it'd take to recover? I'm sure the recovery craft would, but I doubt the "lost" craft would.
Unfortunately this entire idea is probably unfeasable due to this. The risk of missing a tether would be too great, basically a guaranteed loss.
@@fatboychummy bro, we literally already have aircraft that can go that high, and also getting an aircraft to go 12 k kmh rather than 40 or 50 k kmh. If we want an early and efficient space travel machine, this is it.
@@fatboychummy and the cost efficiency would easily overide any lost aircraft, and plus if we actually coordinated the launches, less aircraft would be loose, like airplanes. Finally even this method is till a lot safer than going 40k and crossing your fingers you don't randomly blow up
@@skootties the ships themselves still need rockets to get up to the tethers, so you could have extra fuel in those for course corrections, using a nav computer to calculate the necessary corrections,

Aliens: You are meant to be professional and use warp tech.
Us Humans: Haha, spaceship goes yeet.
No, the eye is not here go away nomai
Haha!
There is one component here (That I can see) that would make this incredibly more difficult than it appears to be.
In their video, Kurzgesagt noted that the tether would (at its lowest point) be at 80-100km going mach 12. For context, the fastest air breathing jet ever built is widely considered to be the SR71 Blackbird, which could climb to an altitude of roughly 85,000 feet (26km) and sustain a speed of mach 3.14. Constructing an aircraft that can fly at about 4 times faster and higher than this while carrying a substantial amount of passengers/cargo would be insanely difficult.
I know Kurzgesagt addressed this in their video too when they said; ""We will need specialized spacecraft to get to the tether, while this isn't exactly easy [its better than rockets]." I just felt like this specific challenge could be covered a bit more in depth.
I still agree with Kurzgesagt that this concept is way better than rockets however, also this was just my 2 cents. I am no aeronautical engineer and if I got anything wrong here then I am open to constructive criticism because I am like everyone else here in that I think it would be cool to learn something new today.

We’ve already experienced tremendous changes in technology on Earth, but going beyond our planet unlocks a new era on the timeline of humanity. If you want to see this stuff happen while you’re alive, make it happen! I believe in you.
The part where this idea was not obliterated down to the ground was surprising, and if that's the case, this is the next big thing related to space I'm really looking forward to.
I can't imagine all the brain-melting calculations and problem solving you would need to be able to catch rockets with one spinning tether orbiting a moving planet or moon to another spinning tether orbiting another moving planet or moon 💀
thats why funding stem is important. astonomy, engineering, and math. plug those into a computer and it now is possible
@@Triobian true, but sadly the government probably wouldnt pour billions to make this idea into a reality anytime soon...
IKR
The physics & maths involved would be soooooooooooo high level and we have to fool proof it
In the end, it's just about the calculation, it needs to be very precise and very reliable. I'd say we've got technology for it, just another C program running with enough computation power. What I'd worry about tho is the dread when on one day, you get production bug, meaning there is a rocket which missed it's sling and is now on its way to exit solar system. That's gonna cause some headaches..
Honestly, I don't think it's all that complicated. You know how much momentum the skyhook transfers when it yeets a payload, because you designed it. You know the mass of the payload, because you approved it. Using those, you can calculate the velocity that the skyhook will accelerate a given payload to.
At this point, it becomes the same as flying a conventional rocket to another celestial body. You can precisely calculate arrival time because the orbits of those celestial bodies don't change. Yes, you're aiming for a moving target from a moving platform, but you know precisely where both you and the target are going to be at any given moment.
Once the payload is at it's destination, you just do the same thing in reverse. You know how much momentum you need to arrest, you know the capabilities of your skyhook. It's basically just a matter of not accidentally over or underspinning the skyhook, which is basically down to good planning and emergency engines.
Kurzgesagt: hope for humanity
Me: *waiting for the drawback*
... ... ...
:D
There's always a drawback! If everything was so peachy about a skyhook like he says, then NASA would already have plans or already implementing it. It's probably high cost, a logistical nightmare, or other reasons.
@@JamesQuintero18 it's highly possible that the idea is new or that it wasn't verified with proper simulations before. Science takes time.
@@satanas1729 It is not as new as you may think. The idea goes all the way back to the 70's. You are correct on the need for technological development. After a study in 2001, NASA said that there are no "fundamental technical show-stoppers" but we are still a long way off from even testing it.
@@themachine9366 You are correct that there have been many tests with tethered satellites. I meant the full scale version. Sorry for the confusion.
one day a giant skyhook will crash on earth.

Yeah Dude obviously... Geez c'mon! am I right Caitlyn! *high five*
Caitlyn April riiiiighhhhttttt
Caitlyn April what an intellectual brainlet
Nice pfp OP
But yes indeed. It's all a matter of the velocity and trajectory of the yeet. Once you've figured that out, there's no limit to how far you'll yeet!

We don't have to wait 1000 years for this to happen. It will probably happen in this century.
Something similar to regenerative breaking could be used to slow down the tether when desired and convert some of the energy back to a battery.

I really hope I'm gonna be around to see stuff like this happen
Sure you will
don't worry you have long life
I hope im not alive to see an idiot investing on this idea.
Do you have sny idea how many rps this tether would have to be spinning while sustaining orbital speed in order to become a viable choice of propulsion? Lol
@@joweydelanota5558 so what are you gonna do make a bunch of expensive reuseable nuclear fueled rocket like elon musk plan? If you want to do that you must use an energy source that is unlimited. Lets say we will need the dysons sphere first before we can do that
@@joweydelanota5558 I mean, do you? Have you done the math? Anyone with basic physics knowledge knows that it is clearly not about the RPS but about the length of the 'arm'. If the hook is long enough, even a really low RPS is enough for meaningful propulsion. Torque is a relation between the length of the arm, the force applied and the sin between the force direction and the radius direction. We are talking about a ~1000km cable with an asymmetrical weight. Also, since we are talking about space, the final velocity achieved by the hook is kept by the vehicle. Since the vehicle mass is way lower than the hook's mass, the energy transferred to the ship is significant.

@@user-bh6cz8kp4q What? Sky hooks are legit possible.
@@Yamyatos Okay so as possible or legit as you might think they are; the challenge of finding the proper balance in momentum, accounting for space debris, manufacturing materials that can handle all that wear without risk of breaking before replacement, not to mention it's really easy to plan this stuff on paper and say yeah that looks good.
I want you to go to nasa or elon and ask for funding for skyhook watch em laugh at you and sit you down and explain how maybe, maaaybe the initial idea was plausable right, but when it gets down to it at the very least you risk causing general instability within the solar systems respective orbits
The solar system as we know it has been altered just by the rockets we've flown to the moon, and the satellites and what have you that we've launched. (Yeah, it hasn't changed anything in any real noticable fashion; yet, but imagine human expansion especially once we're harvesting asteroids)
Now; look at something like the tether, short term, sure its not gonna do much, but if you dont balance that expenditure of energy and the sudden addition and large influx of mass being thrown around that grows over time, and in fact draws on the very planets and moons rotational velocities and momentum to accomplish this.
Not to mention this will affect small orbital bodies such as asteroids/meteors etc., carefully plotted out courses will be altered and will assuredly result in earth strikes that will need to be prevented. Let me guess, y'all gonna throw a nuke at it with a tether?
@@sdrawkcabmodnar Nobody is saying it's super easy, and all you just said is rather common knowledge concerning some / most space travel methods. However, while earth may not be the ideal place for it (not saying it's impossible) due to space debris, scientists write paper about the physical capabilities of these systems since the mid 20 century. So while you may not get funding for it until we solved a couple problems and concerns, if you say it's an idea without a future, you are disagreeing with the scientific consensus.
Better yet you could have 2 skyhooks. A small one that delivers you into low orbit and a really big one that throws you towards a planet. You could have a very large dedicated space ship that gets caught by the big hook, slowed down and released into low earth orbit. There it would exchange passengers and cargo that were brought up in a different ship by the small hook, before being picked up again and thrown at a planet. That way, each ship could be more specialised which would save on costs, allow for more room in the big ship and you could even turn the ship into centrifuge using the teather and weight design which would insure no one suffered from bone degeneration. Also, because the big skyhook would be out of the way in a large orbit and not have to withstand the atmosphere, it could be alot biger and spin much more quickly which would increase speed and further reduce travel times.
Every time I watch one of these videos I grow evermore determined to become an Aerospace Engineer. I think if I can work for NASA and help bring us just one step closer to our future in the stars, I’ll have done what I was spawned on this space rock to do

Best reason to have high atmospheric refueling is getting a station on the moon. We need an industrial infrastructure to build orbital platforms. I wish we invested in a rail lift platform. The US has a perfect launching region that most of the world lacks. The desert of the southwest US is ideal for it.
Use fuel as the tether weight, refuel as you get flung!
Wow, just thinking about it, when tall ships and sails were around, took around 2 months or more to cross a large part of the ocean. Now we are crossing space in that time frame.
I would've liked to hear some disadvantages or challenges from using that method to transport
There simply isn't one
Where's the: "So what's the catch?" part of the video?
The catch is how difficult it would be to catch the payloads.
I assume its probably such a new idea that its taking time to impliment.
I was wondering that too
The catch is the tether catching the rockets, hehe. Don't get it?
Hello
NASA: every decade we will make a new space shuttle

Space Shuttle program was stopped after Atlantis' final flight about 7 years ago. USA has relied on the Russian Soyuz spacecraft since then.

@@heyboss1684 the first part didn't seem like a joke, but I get the second part. Just wanted to inform you about the space shuttle program.
This piece offers a fascinating glimpse into the potential future of space travel. The concept of the Skyhook and its implications for space infrastructure are both innovative and thought-provoking. It's exciting to consider how such advancements could make space exploration more accessible and affordable for humanity.
You forgot to mention something though. If the calculations of timing are wrong or if there are malfunctions in the tether. Me may be Yeeted to the sun instead
Maybe not to the sun, but i agree, one tiny mistake and you can miss your destination tether and end up flying forever in cosmic emptiness

I never thought that yeeting spaceships into space would be a good idea
I think there is a small issue when using just tethers. The rotational force can just be transmitted to the tip of the leverage, if its solid from the rotating center to the catching hook/ end pice. If youre just yousing flexible tethers, the rotating satalite will just wind up like a jojo.
And let say its solid, its not just the the rotation that will be slowed down, when the hook enters the atmosphere, it will also shift the rotation point away from the center of the satelite, towards earth, so the satelite will be pulled back to earth. Its like dropping a stick into water out of a fast driving boat. As soon as the lower end of the stick touches the water, the upper end will be rotated into the water. Perhsps not that extreme, but just wanted to give my point an reverable example.
One could say that a space cable would be _a stretch..._

Titan has metric craptons of methane already cooled and pressurized into a liquid. Methane is a simple enough chemical that it can form abiotically.
😂
That planet is in serious need of Democracy all of a sudden.
This is such a genius idea! I think this will work!
Have feasibility studies been conducted on this? For this to be taken seriously you’d have to do the following experiment:
1) make a short version of the tether out of the candidate material
2) hook said tether to a device that will keep it under tension equal to what a tether in space would
3) fire a few projectiles at a similar speed to what micrometeorites in the area would be at the tether and show that it still holds within acceptable safety margins.
4) expose the tether to radiation consistent with what a space tether would experience and show it will hold up to it for a reasonable period of time.
5) perhaps most important, repair the tether of both radiation and collision damage while it is still under tension. This can be either fixing the existing materiel, or replacing a segment of it, so long as the tension of the whole tether is maintained throughout.
Has this sort of test been conducted?
Is anyone else getting super enthusiastic about things like that and almost mad that they’re not being done already ?

the peasant's sling is apperantly the ultimate technology. why stick to just throwing rocks when you can throw SPACESHIPS
Forget skyhook, orbital ring(s) is where the magic is.
It remove all the constraint from grabbing flying at dozen of time of the speed of sound,
It can grab object directly from the ground at zero speed,
It can grab object from space by matching their speed instead of them matching his,
If you take your time the cargo don't even need aerodynamic shape,
It doesn't require an incredibly tight timetable, you have full control over how long you keep it in place.
It can propel its cargo to any speed without needing to change its shape,
It don't take over multiple orbits worth of satellites & stations, reducing the risk with debris,
It can be used to grab debris since it can match speed with grossly anything.
It can be stopped entirely for maintenance with zero stress on the structure and little energy to maintain it,
It only use electricity and any mass can be used to restore the used kinetic energy,
It doesn't require magic metal like space elevator and is far shorter to build, it is even smaller than the biggest skyhook concept shown,
It is structurally literally a magnetic train/crane/catapult on a very long, fairly simple rail of plain metal in orbit.
Once built the first generation of orbital ring will build the second, even bigger and from there outpace economically anything else.
And did I mention you could have several train/cranes working on the same ring and multiple rings on multiple orbits?
the world would be 1000x more advanced if kurzgesagt ran it
Problem: It's expensive and inefficient to use rockets to send stuff to space.
Scientist (possibly high): "What if we, like, threw the rockets real hard?"
*yeet the rockets real hard
*Elon Musk on weed

Haha then you ask them if they ever heard of the ISS. Plus, if it entered the Earth’s atmosphere it would likely burn up before it hit.
Tbh they could maje it so that it does not pass over populated areas or at least areas where these types of pricks are non existant
But they let airlines fly over their house.
same people who don't realize there are thousands of satellites in the sky
Thanks for the video!
Hi I am in third grade of aerospace engineering and I would love to do research about skyhook's infrastructure, I hope that one day I could go back to this comment and see whit my own eyes that this thing are real. Thank you for all your awesome work and letting us to discover this marvels :)
“All roads lead to rome”

Lol yeah but what does Mars look like
First you need to find mars, so you could travel back to earth...

Theres always gonna be someone trying to mess with the tether. There ALWAYS is.

I was waiting for the "BUT"
Mr.Choklad *cough* Elon musk
BUT, Boeing's Hypersonic Airplane Space Tether Orbital Launch (HASTOL) study concluded that substantial improvement in technology would be needed. In particular, there was concern that the best available material for the tether, Spectra 2000 (a kind of ultra-high-molecular-weight polyethylene), would be rapidly eroded by atomic oxygen.
@@cowlinator consider a sheath of vacuum sealed material around it? The sling will need some mechanism for moving the payloads up and down anyway.
But climate change will kill all of us before that.

Fantastic idea that we should implement as fast as possible.
this is an brilliant idea since its so cheap and not too hard to construct.
2050 math teacher:
If the teather crosses the north pole at 5am at 500kmh and the spaceship takes of from Iceland at 4am at 250kmh . Calculate the speed and angle that should be taken for the ship to land safelly at the moon station by noon. Justify your answer.
